ACTION REQUESTED 
Request Commission authorization for the Chief Executive Officer to advertise and award two
major public works contracts  for the  (1)  renovation of Port-owned field offices, and
(2) construction of bus stops with off-airport security facilities in the contractor parking lot as
part of the Construction Logistics Expansion project at Seattle-Tacoma International Airport for
an additional $2,685,000. 
SYNOPSIS 
With the increasing capital construction program at the Airport, the existing construction
logistics facilities need to be reconfigured. These facilities currently provide space for contractor
parking, temporary construction trailers, and the delivery and storage of materials and equipment
for both Port and tenant projects. In addition, the Port owned field offices need to be improved to
keep them in operation in support of the capital construction program. In September 2015, the
Transportation Security Administration (TSA) issued a security directive that requires the full
inspection (including examination of backpacks, tool bags, etc.) of anyone accessing the secure
areas of the Airport. In order to meet this requirement , avoid significant impacts to Airport
operations, and reduce Port project costs, bus stops with off-airport security facilities will be
constructed in the contractor parking lot. 
This is the third and final Commission request for this project. The Commission previously 
authorized $6,915,000 in two actions for the design and construction of the contractor parking
relocation, the design and construction of the construction laydown reconfiguration, and the 
design of the field offices renovation. This request is to construct the field offices renovation and
add bus stops with off-airport security facilities in the contractor parking lot under two separate
major works contracts. This request requires a $2,383,748 capital budget increase to cover

additional scope for unknown conditions for the field office renovation ($550,000), the addition
of the bus stops with off-airport security facilities in the contractor parking lot ($2,180,000), and
less project savings for the completed work and work under contract. 
BACKGROUND 
The construction logistics facilities were originally constructed in 2001 at the Logistics site (see
Attachment A) located near 28th Avenue South and South 192nd Street. It included a560-stall 
contractor parking lot, and six construction laydown areas providing 12 acres of support space.
The logistics facilities have been used by contractors working on both Port and tenant
construction contracts. The contractor parking lot is used for construction worker parking and
loading workers onto buses for transport to construction sites.  The construction laydown areas
provide contractor space for both temporary construction trailers (remote field offices) and the
delivery and storage of materials and equipment. Typically, 2-3% of the contractor's bid costs
are associated with providing construction logistics for a project. By providing these nearby
facilities, these costs are reduced to 1-2%. Based upon the committed Aviation capital program,
1% of the anticipated contractor bid costs is estimated at $13 million. 
In 2010, the Bus Maintenance Facility was constructed in a portion of the Logistics site, reducing
the available construction laydown area from 12 to 7.7 acres. With the expansion of the Aviation
capital program, the construction logistics facilities require reconfiguration to provide 900
parking stalls and a total of 9.6 acres of construction laydown space. 
The Port's logistics facilities also include field offices at the Water Tower, West Side, and
Logistics sites (see Attachment B). The Central Procurement Office, Construction Management,
Survey, and Construction Safety currently have office space at each of these field office
locations. These facilities consist of trailers that are more than ten years old and require
renovations in order to remain usable for an additional 10 years in support of the Aviation capital
program. 
This project is being completed as four separate efforts as described below: 
1.  Contractor Parking (Complete) 
The relocation of the contractor parking area from the current logistics site to the closed South
Employee Parking Lot (SEPL) located just north of the existing facility was completed using a 
combination of Port crews and small works contractors. This work was completed under budget 
for $370,000. 
2.  Construction Laydown (Complete/Under Contract) 
The existing construction laydown facilities at the Logistics site need to be reconfigured in order
to maximize the available usable space to support the Aviation capital program. In addition, the
SEPL storm water management facilities require upgrading to meet current permit requirements.
This work was split into two phases to support the anticipated Aviation capital program
construction schedules. Phase one (the reconfiguration of Lots 1 and 2) is complete using a

COMMISSION AGENDA

combination of Port crews and small works contracts. Phase two (remaining scope) is under
contract to be completed in 2016. The total forecasted cost for both phases is under budget at 
$5,050,000. 
3.  Field Offices (Current Request) 
The renovation of these facilities was originally estimated at a total cost of $1,450,000 before
design started. Design of these improvements was previously authorized by the Commission on
October 28, 2014, and is now 90% complete. The total estimated cost of the renovation has
increased from $1,450,000 to $2,000,000 due to the knowledge of previously unknown condition
of the heating and ventilation systems, the need to replace the access ramps at the Logistics (a
previously defined risk due to their poor condition) and West Side field offices (regulatory
access requirement), and the addition of fall protection on the field office roofs to meet current
safety requirements. This authorization request includes the construction of these improvements. 
4.  Contractor Parking Bus Stops with Off-Airport Security Facilities (Current Request) 
In September 2015, the TSA issued a security directive requiring full inspection of everyone
accessing the secure Airport operations areas, including examination of backpacks, tool bags,
etc. Based upon the current Aviation capital program, staff forecasts 300 to 400 construction
workers will be transported each day by bus between the contractor parking lot and project sites 
within the secure areas of the Airport. To efficiently and effectively accommodate these new
requirements, and to avoid significant impacts to Airport operations if construction workers were
to be inspected at the airfield access gates, staff recommends adding off-airport security facilities
at bus stops for the full inspection of construction workers.  The total estimated cost for
constructing these added improvements is $2,180,000.  This investment enables saving an
estimated $2.3 million in operational delay costs at the airfield access gates caused by the
forecast contractor busing activity over the next eight years.  The completed facilities also
represent less of a bid cost risk to the Aviation capital program due to the new inspection
requirements and associated construction labor work hour implications. 
Sustainable Airport Master Plan 
The Aviation Division is underway with the Sustainable Airport Master Plan (SAMP) and
alternatives have been identified that may displace all or portions of the Construction Logistics
facilities in approximately ten to fifteen years. The development of alternative Port-owned
property for construction logistics facilities was explored during the planning phase of this
capital project. The other sites evaluated have the same risk of displacement by future SAMP
development, but costs were substantially higher (estimated at $10 million  $15 million 
depending upon the site). Staff recommends proceeding with the current reconfiguration as the
best lowest cost approach. 
PROJECT JUSTIFICATION AND DETAILS 
The existing construction logistics facilities at Seattle-Tacoma International Airport will be
heavily utilized during the construction of the Aviation capital program in order to limit impacts

to on-going Airport operations. With the increase in the Aviation capital program over the next
10 years the existing construction logistics facilities need to be reconfigured to include a 900-
stall contractor parking lot and 9.6 acres of flexible construction laydown space. In addition, the
field offices that house up to 140 Port staff in support of the Aviation capital program are over 10
years old and need to be renovated in order to keep them in operation for the next 10 years. 
Project Objectives 
Provide sufficient construction laydown and contractor parking facilities to support the
anticipated Aviation capital program for the next ten years. 
Upgrade the existing SEPL storm water management facilities to meet current permit
requirements with no impact to the existing streams, wetlands, and associated buffers. 
Maintain existing field offices to provide an effective work environment for Port staff. 
Minimize investment in facilities that may be displaced by future project actions. 
Minimize the impact to airport operations. 
Minimize the impact of security requirements to airport construction projects. 
Scope of Work 
The project includes the reconfiguration of the construction logistics facilities, the re-use of
SEPL as a contractor parking lot, the upgrade of the SEPL storm water management facilities,
the renewal of the remote field offices used by Port staff, and the construction of bus stops with
off-airport security facilities  in the contractor parking lot. The key elements include the
following: 
Contractor Parking (Complete): SEPL was originally constructed in the late 1980s and has
not been in use for several years. In order to get the facility back into operation to support
contractor parking, the lot needed to be cleaned, restriped, signed, existing potholes and
damaged curb sections repaired, and the access control system replaced. 
Construction Laydown  (Complete/Under Contract): The Logistics site needs to be
reconfigured in order to maximize the use of the space and support a larger number of
temporary construction trailers. The redevelopment of the construction laydown facilities
includes utilities (power, communications, water, and sewer), trenching, pavement patching,
striping, lighting and bollards.
SEPL Storm Water Management Facilities (Under Contract): SEPL includes two storm
detention ponds and a bio filtration swale that were constructed as part of the original
facility in the late 1980's. The bio filtration swale needs to be upgraded to meet current
permit requirements for water quality. 
Field Offices (Current Request): Improvements differ by location but generally include the 
replacement of the heating and ventilation systems, hot water heaters, roof ladders, and
access ramps, roof membrane upgrades, addition of fall protection, and exterior repair and
repainting. There are two vacant facilities at the West Side location that will be demolished
as part of this effort.

Lifecycle Cost and Savings 
Port staff does not anticipate a significant change in the on-going operation and maintenance
costs associated with the construction logistics facilities and remote field offices. These costs 
have ranged from $40,000 to $55,000 annually and will continue to be incorporated into the
Aviation capital program costs through allocated overhead. The additional operating costs for
security inspections will be paid by the capital projects utilizing the bus stops in the contractor
parking lot. 
STRATEGIES AND OBJECTIVES 
This project supports the Century Agenda's strategic objective to advance this region as a
leading tourism destination and business gateway since this project supports the Aviation capital
program, which in turn provides the facilities necessary to meet the region's air transportation
needs at the Airport. 
This project also supports the Aviation Business Plan strategies to operate a world-class
international airport by anticipating and meeting the needs of our tenants, passengers and the 
region's economy, and to reduce airline costs as far as possible without compromising
operational and capital needs. This project supports the Aviation capital program, which in turn
provides the facilities necessary to support Airport operations. This project also focused on reutilizing
existing facility assets in order to minimize the overall cost impact. 
TRIPLE BOTTOM LINE 
Economic Development 
The Construction Logistics Expansion project supports the Aviation capital program, which 
represents an investment in our current facilities and supports the long-term vitality of the
Airport and its tenants.

Environmental Responsibility 
The Construction Logistics Expansion project will upgrade existing storm water management
facilities to meet current permit requirements.  In addition, the field office renovation will
upgrade existing heating and ventilation units with high efficiency units using a chlorine-free
refrigerant.
Community Benefits 
The Construction Logistics Expansion project will provide construction logistics facilities for the
Aviation capital program, which will reduce the impact to existing Airport operations, and
provide an increased level of service for passengers and the traveling public. In addition, staff
will work with the Office of Social Responsibility to determine small business participation
opportunities, in accordance with Resolution No. 3618. 
ALTERNATIVES AND IMPLICATIONS CONSIDERED 
This Commission authorization request includes two separate efforts and the alternatives are
grouped by each effort. The following alternatives were considered for the renovation of the
field offices. 
Alternative 1)  No Field Office Improvements 
Under this alternative the reconfiguration of the construction logistics facilities (including the
storm water management facilities) are completed but the field offices are not improved. The
existing facilities would remain in use in their current condition. The total estimated cost for this
alternative is $565,000 and represents the design costs to date and anticipated closeout costs.
This is not the recommended alternative. 
Pros: 
This is the lowest project cost alternative. 
Cons: 
The field offices would not be renovated and the facilities would continue to degrade
making them eventually uninhabitable for work. The heating and ventilation system
has already failed at one field office location and the roof system is leaking at two field
office locations. 
Alternative 2)  Complete the Field Office Renovation 
Under this alternative the existing field offices are renovated. The total estimated cost for this
alternative is $2,000,000 and would be completed by Q4 2016. This is the recommended
alternative. 
Pros: 
The field offices would be renovated in order to extend their useful life

COMMISSION AGENDA 
Ted Fick, Chief Executive Officer 
February 16, 2016 
Page 8 of 10 
Cons: 
Port staff remains unconsolidated in three locations. 
Alternative 3)  Relocate the Field Offices Off-Site 
Under this alternative the existing field offices would be demolished and staff would be relocated
off-site into leased office space. The total estimated cost for this alternative is $5,438,000 and
would be completed by Q4 2016. This is not the recommended alternative. 
Pros: 
Port staff currently located in the field offices would be centralized in one location. 
Cons: 
This alternative represents the highest project cost (all expense) for the field offices and
includes the demolition of the field offices, buildout of the office space, and one year's
lease (estimated at $874,000) for the office space. 
The following alternatives were considered for the meeting the construction worker security
inspection requirements. 
Alternative 4)  Construction Worker Inspection at Airfield Access Gates
Under this alternative the reconfiguration of the construction logistics facilities (including the
storm water management facilities) are completed and additional facilities are not provided to
support the new security requirements. The total estimated co st for this alternative is $50,000
and represents the design costs to date and anticipated closeout costs.  This is not the
recommended alternative. 
Pros: 
This is the lowest project cost alternative. 
Cons: 
Construction workers would be inspected at the airfield access gates creating significant 
operational impacts (estimated delay costs of $2.3 million), and require additional staff
(estimated at $150,000 annually) to support gate operations. 
The additional security requirements represent a bid cost risk to the Aviation capital
program of $7.3M for this alternative. 
Alternative 5)  Widen 28th Avenue South 
Under this alternative 28th Avenue South would be widened to provide a left-turn lane for
vehicles entering the airfield at Gate E-45. The widening is intended to allow the contractor
buses to bypass the general airfield gate traffic, and enter at their own designated gate. The total
estimated cost for this alternative is $1,880,000 and would be completed by Q1 2018.  This is
not the recommended alternative.

COMMISSION AGENDA 
Ted Fick, Chief Executive Officer 
February 16, 2016 
Page 9 of 10 
Pros: 
This is a lower project cost alternative. 
Cons: 
The widening of 28th Avenue South would not be completed until Q1 2018, which
would not support the Aviation capital program. Current schedules show the startup of
contractor busing in Q4 2016.  Gate operations would be significantly impacted
(estimated delay costs of $0.6M) until the improvements are complete. 
The dedication of one of the entrance gates at Gate E-45 for the contractor buses
requires additional staff (estimated at $150,000 annually) to support gate operations. 
The additional security requirements represent a bid cost risk to the Aviation capital
program of $7.3M for this alternative. 
Alternative 6) - Complete the Bus Stops with Off-Airport Security Facilities 
Under this alternative the bus stops in the contractor parking lot are completed and include
security facilities. The total estimated cost  for this alternative is $2,180,000 and would be
completed by Q4 2016. This is the recommended alternative. 
Pros: 
The bus stops are constructed in the contractor parking lot to support the inspection of
construction workers to meet security requirements and minimize the impact to Airport
operations 
This alternative minimizes the bid cost risk to the Aviation capital program due to the
additional security requirements. 
Cons: 
This is a highest project cost alternative. 
Alternative 7)  Complete the Bus Stops using Mobile Security Application 
Under this alternative the bus stops in the contractor parking lot are completed. However, under
this alternative, the communication infrastructure is not included in the bus stop scope of work
and a mobile security application is used to check badge requirements. The total estimated cost
for this alternative is $1,520,000 and would be completed by Q4 2016.   This is not the
recommended alternative. 
Pros: 
This is a lower project cost alternative. 
The bus stops are constructed in the contractor parking lot to support the inspection of
construction workers to meet security requirements and minimize the impact to Airport
operations. 
This alternative minimizes the bid cost risk to the Aviation capital program due to the
additional security requirements.

COMMISSION AGENDA 
Ted Fick, Chief Executive Officer 
February 16, 2016 
Page 10 of 10 
Cons: 
The removal of the communication infrastructure from the bus stop scope of work
removes the access control equipment and cameras and reduces the project cost by
$660,000.  The new mobile security application can be used to check badge
requirements; however, compliance with the Airport security plan and Port employee
safety cannot be monitored.
Under this alternative there is risk that the TSA will not approve the required
amendment to the Airport security plan to implement the remote inspections without
the cameras since these facilities will be in use for more than three to five years.
